To raise construction productivity and

fundamentally change the design and

construction processes, BCA

encourages the industry to embrace

the concept of Design for

Manufacturing and Assembly

(DfMA), where construction is

designed such that as much work

may be done offsite in a controlled

manufacturing environment as

possible.

PPVC (Prefabricated Prefinished Volumetric Construction)

23

What is PPVC?

PPVC? – Prefabricated Prefinished Volumetric Construction

PPVC involves the assembly of whole rooms / units, complete with

internal finishes, fixtures & fittings, that are produced offsite and

installed onsite in a Lego like manner.

What is PPVC?

Conclusion

26

Singapore Construction is Evolving with DfMA

Traditional method of construction

is labour intensive and time

consuming

Productivity needs to be

considered upfront in design

DfMA paves the way for superior

construction productivity

PPVC is expected to become the

new norm in Singapore
